a) Three equivalent charges 2.0 micro coulomb each, are held fixed at the three corners of an equilateral triangle of side 5 cm. Determine the Coulomb force experienced at its centre.
b) An electric field of 20N/C exists along the X-axis in space. Measure the potential difference VB-VA where the points A and B are given by (a) A = (0,0) and B = (4,2) metre.
(b) A = (4,2) meter and B=(6,5) metre.
Q. What is quantum mechanical "Tunneling"? Give one example. OR What do you mean by quantum mechanical tunneling? Show that the tunneling probability is given by the
A quantity that can be calculated by instrument, clearly defined and has proper units is known as physical value. Physical quantities are described as fundamental and derived quant

Light is quantized. Photons are light quanta. It has zero REST mass. Therefore, it always travels at maximum speed permitted by relativity.
Rutherford's alpha-scattering experiment recognized that the mass of atom is concentrated with small positively charged region at the centre which is known as 'nucleus'. Nuclei
Describe how tunneling takes place When tunnel diode is forward biased, its initial behaviour is similar to that when it's reverse biased. Now, some of the fille
